Archaeological Significance
Formation
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.

More about Granulite and Breccia
Here you can know more about Granulite and Breccia. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Breccia consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Breccia includes Calcite, Clay, Feldspar, Phosphates, Quartz, Silica. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Breccia, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors. Appearance of Granulite is Veined or Pebbled and that of Breccia is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Granulite vs Breccia. The hardness of Granulite is 6-7 and that of Breccia is 7. The types of Granulite are Metamorphic rock whereas types of Breccia are Collapse Breccia, Fault Breccia, Flow Breccia, Pyroclastic Breccia, Igneous Breccia and Impact Breccia. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Breccia is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Breccia is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granulite is heat resistant, wear resistant whereas Breccia is heat resistant, impact resistant, pressure resistant, wear resistant.
